All of the staff were incredible! Ophelia was extremely attentive to our diving needs; she started off by asking if there were any things we struggled with or were apprehensive about. She was very kind. Yann was also extremely helpful with a health issue we encountered and was very reassuring.
Honestly if I had all the time in the world I would write about all the staff. They really made the trip special.
